Here's a very preliminary Celestia Addon, showing the World and its planetary system. The Addon includes planetary maps generated by a demo version of Fractal Terrains plus my own colored height-map of the planet's surface.

I expect to be improving my version of the map, but it's become clear that'll be a long-term project.

To see this addon, restore (expand) the Zip file into Celestia's "extras" directory. It includes "readme" files explaining more about it. Celestia is available for free for Windows, MacOS and Linux at http://sourceforge.net/project/showfiles.php?group_id=21302
